#### Answer

$46^{\circ},78^{\circ},56^{\circ}$

#### Work Step by Step

1. $\angle B= \angle M= 46^{\circ}$
$\angle C= \angle P= 78^{\circ}$
These angles are marked as congruent and therefore have the same measure
2. To get final angle we need to remember that angles in a triangle sum up to 180 degrees
$\angle A= \angle N= 180^{\circ}- 46^{\circ}- 78^{\circ}= 56^{\circ}$
